After various reports Britney used a body double for her Hold It Against Me music video, a "leaked" rehearsal video has hit the 'Net proving Britney does, in fact, do at least some of her moves.

The once super fab dancer marked her moves for a number in her upcoming tour but all this seems to prove is that Brit can do the easy stuff and that when it comes to real, all-out dancing, she hires a stand-in.

This woman is believed to be choreographer's assistant Tiana Brown wearing a blonde wig in the Hold It Against Me clip.

Now no one has claimed Britney didn't do her own dancing in 'Till the World Ends but does it compare with her old stuff??? Check out that clip after the jump ...
